SPECIFICATION forming part Of Letters Patent No. 499,415, dated June 13, 1893.

Application filed February 17,1893. Serial No. 462,718. (No model.)

To all whom it may concern.-

Be it known that we, EDUAR-D A. CARDINAL, residing at Kirkland, and JAMEs- LovE, residing at NewCastle,in thecountyof Kingand State of Washington, citizens of the United States, have invented certain new and useful Improvements in Cultivators; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Ourinvention relates to an improvement in cultivators, and particularly to that class known as wheel cultivators, or those wherein the cultivator is supported upon large carrying-wheels; and our object is to produce a more durable and efficient arrangement than any heretofore known, and one in which the body of the cultivator may be adjusted to suit the exigencies of the work to be performed.

A further object is to construct a cultivator wherein the body of the machine, its teeth and attachments are suspended from the axle, and to provide efficient means for raising or adjusting such body.

To these ends our invention consists in certain novel features of construction and com binations of parts more fully described hereinafter, and finally embodied in the claims.

Referring to the accompanying drawings which represent a cultivator embodying the essential features of our invention: Figure 1, represents a plan view thereof; Fig. 2, a side elevation; Fig. 3, a rear elevation; Fig. 4, a detail view showing the mechanism for operating the knives; Fig. 5 a view in detail showing the manner of affixing the teeth to the frame.

The reference letter A indicates the frame of our cultivator which is preferably rectangular in form, and provided with the braces A located at its corners, and the longitudinal brace A both of which are designed to insure strength and durability. Extending across this frame are two lateral beams B and B the latter being provided with braces B J ournaled in the beams B and B and the Fulcrumed to the beam B are two hand-levers D, which extend vertically and are provided with the pawl and ratchet attachment D fixed to the beam B. These levers are pivotally connected to the rod d, so that they may be moved laterally within the limit of the movements of the lever D, for a purpose which will be hereinafter explained. Rearward of the beam B, the frame A drops below the level of the rods 0 and O and continues to extend out rearwardly therefrom. Located on this portion of the frame, parallel to each other, and to the beam B, are two cross-beams E. These beams are secured in position by means of the semi-circular rods E, which are securely fastened to the frame A and its longitudinal brace A A bolt e is also provided to hold the beams E in position, which bolt extends to the frame A and brace A and is provided at its upper end with a thumb-nut e, which may be removed to admit changing the position of the beams E as shown in dotted lines, Fig. 5, and as will be more fully described later on.

Secured to the beams E in any preferred manner are the cultivator teeth or spades F, which are of the usual construction.

The reference letter G indicates the axle of the cultivator, which is of the usual construction, that is: having at its ends the downwardly extending port-ion G, from which the axle proper G2 projects laterally. Upon these axles the wheels G are mounted.

Securely fastened to the downwardly ex tending portion G of the axle is a vertical rod H provided with an elongated slot H, extending its entire length below the portion G2 of the axle.

Rigidly secured at each end of the beam B adjacent to the rod H, is a lug I, provided with a reduced end I which is adapted to enter the slot H in the rod H, and is secured therein by a nut working on its outer end.

Fixed to the main portion of the axle G, and extending forward therefrom at an angle of about forty-five degrees are two arms J, in

which is journaled a revoluble shaft J. To the ends of this shaft are fixed the sectors J over each of which the suspending chain K operates. The lower ends of these chains are connected to the beam B, adjacent to the lug I, and by which thebody of the cultivator is suspended or lifted.

Keyed to the middle of the shaft J, is a lever L, provided with an arm L extendingbelow the shaft J. To the end of this arm the rod L is connected, the remaining end of said rod being secured to the chain M, working over the pulley M, the latter being connected with the pole of the cultivator. The chain M extends downwardly and has its lower end connected to the forward part of the frame A.

Rigidly fastened to the axle G are the hounds N, which converge and are joined at a point directly over the forward part of the frame A, to the pole or shaft N of the cultivator.

Pivotally secured to the under side of the pole N is a rod 0, which extends downwardly about two-thirds of the distance to the frame A, or the body of the cultivator.

Extending from the forward part of the frame, outwardly and upwardly therefrom,is a second rod 0, the end of which isjoined to the lower end of the rod 0, by means of the clevis P, which is also used to connect the whiftletree P to the cultivator. To this whittletree the draft of the team is applied.

A seat Q is provided for the operator and is securely fastened to the middle of the axle K, in such a position that ready access may be had to the lever L and to the levers D.

The preferred construction of our invention having been described, we will now proceed to set forth its mode of operation.

When itis desired to use our invention for preparing or cultivating land, the knives seon red to the rods C C are adjusted so that they will extend below the frame A and project into the ground. This is efiected by means of the hand levers D, which are connected, as'before explained, to the rods (1. The rods (1 are in turn connected to the rods 0 and O, by means of the Vertically extending links 0, keyed to the said rods O and 0. Therefore, it will be apparent that upon the oscillation of the levers D, the rods 0 and C will revolve or rock in their bearings, which is followed by a similar motion of the knives a. By these means the operation referred to above is effected. The spades or teeth co operate with the knives c, to prepare the ground, when in the position shown by Fig. 2. They may, however, be lifted out of engagement with the ground by loosening the thumb-nut e, and swinging or revolving the beams E, on the semi-circular rods E, whereupon they will assume the position shown by dotted linesin Fig. 5. The teeth are thus arranged so that the cultivator, when moving from place to place, when not engaged in preparing the ground, will notscratch the road upon which the cultivator is moving. When, however, it is desired to transport the cultivator any great distance, the entire frame A and its attach ments, or the body of the cultivator, may be lifted to the desired height by oscillating the lever L, whereupon the shaft .I will rock in its bearings carrying with it the sector J This will be followed by the pulling up of the chains K and a subsequent lifting of the entire frame A, to which the said chains are attached; the lug I working in the slot II, of the rod H, thereby retaining the rigidity of the machine which is characteristic of its normal position. Simultaneous with this operation the arm L, oscillates so as to pull 011 the rod L which is followed by the pulling up of the chain M. This movement lifts theforward part of the body or frame A, and serves to preserve the equilibrium of the suspended parts. To bring the cultivator in the position for working the ground again, the lever L, is simply thrown back to its former position, whereupon the body portion will drop of its own weight into the position shown in the drawings.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a cultivator, the combination of an axle, vertically slotted rods depending therefrom, a tooth-carrying frame secured to the rods and movable in its vertical slots, ashaft revolubly journaled in bearings secured to the axle, a chain connecting the shaft and frame by which the said frame is lifted, and an operating lever fixed to the shaft, substantially as described.

2. In a cultivator, the combination of an axle, vertically slotted rods rigidly secured to the axle and depending therefrom, a toothearrying frame provided with studs fitting in the vertical slots, a shaft journaled in bearings fixed to the axle, segments fixed to the shaft and having chains operating therewith and with the toothed carrying-frame,by which chain the frame is moved in the vertical slots of the rods, and an operating lever fixed to the shaft, substantially as described.

3. In a cultivator, the combination with the frame or body thereof, of a tooth-bar, U- shaped staples, one arm of which fits loosely in openings in the tooth-bar, and bolts for removably securing the said tooth -bar in place, whereby upon removing the bolts the tooth-bar may be swung from one arm of the staples to the other arm, and its teeth disengaged from the ground, substantially as described.

4. In a wheel cultivator, the combination of lii bolts fixed to the rods, levers for rocking and locking said rods, one or more beams located on the body, teeth fixed to the beams, and semicircular bolts for securing the beams to the body, by which the said beams maybe swung or revolved so as to change the-disposition of the teeth, substantially as described.

5. In a cultivator, the combination of an axle, slotted rods depending therefrom, a body portion locatedbelo'w the axle, lugs on the body-portion arranged to slide in the slots in the rods, a shaft journaled in boxes adjacent to the axle, segments on the shaft, chains connected to the segments and body, a lever by which the shaft is rocked, a number of rods journaled in the body portion, blades or knives secured thereto, links fixed to the rods, beams 'to which the remaining ends of said links are the body-portion, teeth fixed thereto, semi-' circular, bolts by which the said beams are secured to the body,.and removable bolts connec'ted to the beams and body,-"substantially as described.
